Abstract CYCLOPS L2 is the tool steel counterpart of one of the widely used chromium-vanadium low-alloy steels. It exhibits exceptional strength, toughness and resistance to fatigue; it may be used where these characteristics are more important than extreme hardness. Cyclops L2 has only modest hardenability but it has good resistance to abrasion and wear in the hardened condition. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on forming, heat treating, machining, and joining. Filing Code: TS-325. Producer or source: Cyclops Corporation.
